    Abstract: A display system with a pointer that is not restricted by wires or sensors. The display uses a spatial light modulator (14) for projecting an image on the screen (20). During a time period when all of the cells of the modulator (14) are in the same state, a cursor projected onto the screen by the pointer is reimaged from the screen to a detector (26), which translates the cursor image into signals for a central processing unit (38). The central processing unit (38) then directs the system as to what tasks are being dictated by the cursor.

    Abstract: PURPOSE: To make the device simple in structure, small in size and high in the brightness of a displayed video and to remarkably improve availability by irradiating a mirror polarization type light modulator with light at different angles of incidence and angles of reflection in the same direction in accordance with two or more tilt angles. CONSTITUTION: Projected lights LR and LB in two colors are allowed to irradiate a first mirror polarization type light modulator 41RB for modulation in time-division according to video data in two colors with different angles of incidence and angles of reflection in the same direction. Also, a projected light LG in colors except two colors is irradiated on a second mirror polarization type light modulator 41G for modulation according to video data in colors except two colors. Then, effective reflected lights corresponding to the video data reflected on the first and second mirror polarization type light modulators 41RB and 41G are synthesized by synthesizing means 43G and 43RB. Thus, the device can be made simple in structure, small in size and high in the brightness of the display video.

    Abstract: PURPOSE: To provide an indication device which is used for a large space light modulator and not restricted by wiring and a sensor. CONSTITUTION: A display system provided with a pointer which is not restricted by wiring and the sensor is provided. The space light modulator 14 for projecting an image on a screen 20 is used for display. While all cells in the modulator 14 are in the same state, a cursor projected on a screen by the pointer is image- formed again in a detector 26 from the screen. The detector 26 converts the image of the cursor into a signal transmitted to a central processing unit. The central processing unit makes a system face a task instructed by the cursor.

    Abstract: PURPOSE: To selectively display OHP image and video image on a screen with a simple structure. CONSTITUTION: A video image modulating means 11 is fitted to a light source 2 and a projecting optical system 10A so that the projected light L1 projected from the light source 2 is formed into parallel beams, and the projected light L1 is modulated to the space light in response to the video image so as to generate the image light L3 of the video image. This image light L3 of the video image is condensed and led to the projecting optical system 10A, and the image light L3 of the video image is projected for display.

    Abstract: A signal transmitting system including an A-D converter for converting an analog input signal to a digital signal and a D-A converter for re-converting the digital signal to an analog output signal is provided with improved fidelity without increasing the number of digital levels and digital bits in the A-D and D-A converters. In such signal transmitting system, the analog input signal is applied to a plurality of voltage level comparators for comparison therein with respective reference voltages which sequentially differ from each other by predetermined voltage increments, the levels of the reference voltages are periodically varied by means of a switching signal, outputs from the level comparators are applied to an encoder which produces a corresponding digital signal, a decoder receives the digital signal and reconverts the latter to an analog signal, and the analog signal from the decoder is added to a switching signal which may be the first mentioned switching signal, or at least has the same period as the latter, to provide a resulting analog output signal which relatively closely corresponds to the analog input signal.

    Abstract: A plasma display panel having cathodes, anodes and trigger electrodes wherein the trigger electrodes correspond to a plurality of discharge electrodes which are sequentially scanned and wherein an insulating layer separates the trigger electrodes and the discharge electrodes and where a constant trigger voltage is supplied until the plurality of discharge electrodes corresponding to the trigger electrode have been activated. In the invention, the trigger voltage is quickly changed and is then returned to an intermediate level and the frequency of a trigger voltage pulse is reduced to one over the number of block discharged electrodes so that the power consumption of the trigger electrodes is greatly reduced and since the trigger voltage is returned to an intermediate level erroneous discharges will not be generated between inactive trigger electrodes and the other discharge electrodes to which data voltage pulses are supplied thus producing a high definition display. The trigger voltage may swing positive and negative directions with reference to an intermediate level and an ON potential low level of the cathodes which sequentially fall to a low level by scanning activation may be set to be the same as the intermediate level. Thus, the absolute value of the trigger voltage applied to the insulating layer or dielectric layer between the cathode and trigger electrodes can be substantially one-half a required value and plus or minus one-half with reference to an intermediate level and a breakdown voltage of the insulating layer can be decreased. Therefore, stable operation will be provided over long periods of time without dielectric breakdown and in addition the insulating layer can be thin and the trigger voltage can be decreased.

    Abstract: A method and apparatus for displaying a video picture on a matrix array of light emitting elements form of m rows and n columns of such elements. The video signal, which is comprised of periodic vertical intervals, each containing successive line intervals of video information, is sampled at a rate of n samples during each line interval. The resultant, n sampled picture elements for each sampled line interval in each vertical interval are stored. During a vertical interval, a given light emitting element, such as the i-th element in the j-th row, corresponding to a sampled picture element in a respective line interval, is energized for a duration greater than a line interval and less than a vertical interval as a function of the brightness of the sampled picture element when that sampled picture element is between and black and peak white levels. In a practical embodiment, a storage circuit stores the n sampled picture elements in each line in an mxn matrix array of storage elements. These stored, sampled picture elements are recirculated on a row-by-row basis periodically, all of the sampled picture elements being fully recirculated in a period which is less than the vertical interval. Each of the m rows of light emitting elements are conditioned sequentially are repetitively, in synchronism with the recirculation of the sampled picture elements in the storage circuit. A reference voltage generator generates a reference voltage of staircase waveform during each vertical interval, the step interval of the staircase waveform being equal to the aforementioned period. During each such period, the brightness of each picture element which is shifted into the first row of the storage circuit is compared to the reference voltage, and the columns of light emitting elements are selectively enabled for a duration that is a function of the brightness level of corresponding sampled picture elements. A light emitting element is energized if it is disposed in a row which is conditioned and in a column which is enabled.
